1. International Law and Municipal Law (Domestic/Internal)

2. General Rule on the Relationship
Art. 27 of the 1969 Vienna Convention:
“A party may not invoke the provisions of its internal law as justification for its failure to perform a treaty. This rule is without prejudice to article 46.”
Art. 46: A state may invoke that its consent to be bound by has been taken in violation of its internal law on competence to conclude treaties (clear violation + concerned a rule of fundamental importance)
But the main question is: “How can we explain use of int law rules by national courts?”

3. “How can we explain use of int law rules by national courts
“How can we explain use of int law rules by national courts?” Int law-Domestic Law
Two Main Approaches to Explain this Relationship
1- Dualist Approach
2- Monist Approach
Under the Monist Approach rules of int law are part of national law unless excluded (presumption of inclusion)
Under the Dualist Approach they are part of national law only if included deliberately (presumption of exclusion).

4. Dualist Approach Two main thesis: There are two main reasons for this:
1- international law and municipal law exist separately and one does not affect the other
2- They are different and independent from each other
There are two main reasons for this:
A- b/c inter-state and intra-state relations are fundamentally different
Relations between state-citizenssubordinationcitizens are dependent
Relations between states are based on equality in principle
B- b/c Norm-creating sources of the two are different
Rules of int lawresult of “common consent”concurring will
Rules of municipal law result of unilateral consent

5. Dualist Approach
If a municipal system accepts Dualist Approach There are three consequences:
1- A rule from one  cannot have effect within the other “No direct implementation”
2- No possibility of conflict of rules
3- If one of these legal orders wants to utilize a rule from the other change the “shape/formalistic structure” of the rule This is called as “transformation”

6. Dualist Approach
“Doctrine of Transformation” Rules of int law do not become part of domestic law until they have been accepted by the state
Therefore int law is not ipso facto (by the very fact) part of national law
A national court cannot directly apply a rule of int law until that rule has been transformed into national law properly
This is the position of UK with respect to rules of int law deriving from int treaties

7. Monist Approach
Main argument: “There is only one single legal order int law and internal law are parts of this whole
They are two separate components of one “law”
There may be a conflict between the two legal systems for most of them int law is superior  has priority over the domestic law

8. Monist Approach Possible consequences:
1- implementation of one in the other automatic
2- “Doctrine of Incorporation”:
 “a rule of int law becomes part of national law without a need of clear acceptance by domestic authorities”
 Such rule is automatically incorporated automatic adoption unless there is a provision of national law which precludes the use of such rule by the national court (presumption).

9. Monist Approach Exp: German Basic Law Art. 25: Exp: Netherlands
“Article 25 [Primacy of international law]
The general rules of international law shall be an integral part of federal law. They shall take precedence over the laws and directly create rights and duties for the inhabitants of the federal territory.”
Exp: Netherlands

10. Monist Approach-Netherlands
According to Dutch Cons.All internal law, even constitutional law must be disregarded if it is incompatible with the provisions of treaties or decisions of international organizations that are binding on all persons
Dutch courts must overrule acts of Parliament on the ground that they may conflict with certain treaties or resolutions of int organizations
But Dutch Parliament must consent to treaties which conflict with the Const. by a majority necessary for const amendment

11. Two important questions:
1- The way rules of int law are made part of domestic legal system? Capacity of individuals to invoke such rules before national courts?
2- Legal effect (force) of such rules in domestic law
We will use Turkish legal system as an example Art 90 of the Turkish Constitution

12. Turkish System
Turkish system is mainly Dualist because int treaties should be subject to a process of ratification (transformation) to have effect in Turkish Law
Process: Council of Ministers  Turkish Grand National Assembly  Ratification of treaties shall be subject to adoption by the TGNA by a law approving this ratification (uygun bulma kanunu)
This law is sent to the President for its adoption
Art. 104 int agreements shall be binding for Turkey with their adoption by the President

13. Turkish system Two categories of treaties:
A- Treaties that can be put into effect through promulgation by the Council of Ministers
regulating economic, commercial and technical issues
Agreements for the implementation of a previous treaty
B- Treaties that can be put into effect only through a law from the parliament (ratification) normal procedure why?

14. Turkish system Legal force (value) of Treaties in Turkish Law:
Art. 90 Constitution:
“The ratification of treaties concluded with foreign states and international organisations on behalf of the Republic of Turkey, shall be subject to adoption by the Turkish Grand National Assembly by a law approving the ratification.... International agreements duly put into effect carry the force of law. No appeal to the Constitutional Court can be made with regard to these agreements, on the ground that they are unconstitutional”
Amendment in 2004 “International agreements duly put into effect bear the force of law. No appeal to the Constitutional Court shall be made with regard to these agreements, on the grounds that they are unconstitutional. In case of contradiction between international agreements regarding basic rights and freedoms approved through proper procedure and domestic laws, due to different provisions on the same issue, the provisions of international agreements shall be considered.”
Mainly “transformation”

15. Turkish System
Treaties shall have the force of law but exempted from constitutional review a privileged position Why?
But rules of international law deriving from Arts 15, 16, 42 and 92 of the Constitution (examined below) have constitutional force
What about the principle “lex posterior”?
Technically possible but reserved position for human rights treaties

16. Exceptional cases for Turkish System
Some rules of international law (treaties + general principles of law + customary rules) are directly applicable (self-executing) in Turkey without a need to transform:
Art
With reference to rules of international law in these limited areas certain rules of int law are deemed to be “incorporated” in Turkish legal system

17. Exceptions
Art. 15: in time of war, mobilization, martial law or state of emergency exercise of fundamental rights and freedoms can be partially or entirely suspended provided that obligations under int law are not violated.
Art. 16: Fundamental rights and freedoms of foreigners may be restricted by law in a manner consistent with international law

18. Exceptions
Art. 42 No language other than Turkish shall be thought as a mother tangue to Turkish citizens at any institution of traning or education “but the provisions of int law are reserved” (Treaty of Laussanne)
Art. 92 the power to authorize declaration of war is vested in the Turkish Parliament but restricted to cases deemed legitimate by international alw
Art. 92 Power to send Turkish armed forces to foreign countries and to allow foreign armed forces to be stationed in Turkey is vested to Turkish Parliament but this power is subject to the provisions of international treaties to which Turkey is party to (NATO and treaties for US bases)

19. International law and domestic law
How about the attitude of Turkish Courts?
Different system in the UK:
Accepts “transformation” for treaty law
Accepts “incorporation” for customary rules of int law
Parliamentary sovereigntyNo sitting Parliament can bind the successor Parliament nor be bound by the predecessor
Before 1998:
Treaties were not self-executing-giving no right to invoke before courts (not enforceable before UK courts)
Obligations created over UK at int law level while no such obligation on British Parliament or Courts
Parliament and courts very rarely made use of the jurisprudence of the ECtHR

20. UK After 1998 The Human Rights Act of 1998
Does not incorporate the ECHR (as was the case in 1972 European Communities Act);
Lists articles of the ECHR and calls them as «Convention Rights»
Government’s responsibilityCompatibility of proposed bill with Convention rights;
«To the extent that it is possible to do so»Legislation must be read and interpreted in a way COMPATIBLE with the Convention RightsBUT if the legislation is clear and does not allow such an interpretation!!!
1998 Act empowers some courts to make «declaration of incompatibility»consequences? This does not affect validty or enforcability governmentremedial orderfast trackultimate decision rests with the Parliament

21. UK “Executive certificates” in UK
In UK a court must ask a certificate from the government on a factual matter or a question of international law
Whether an entity is deemed as a “state” by the UK government or not? to be consistent
Domestic court cannot inquire int law to see if the rules related to statehood are satisfied this is determined by the executive certificate
